12 Claims.

This invention relates to an improved container.

This application is in part a continuation of my copending application, Serial No. 78,966, filed May 11, 1936, entitled Container and of my copending application, Serial No. 82,435, filed May 29, 1936, entitled Fiber containerf One of the objects of the invention is to provide an improved fibrous container.

Another object of the invention is to provide an improved fibrous container having reinforced end edges.

Another object of the invention is to provide4 an improved fibrous container having reinforced end edges, sealed against capillary attraction of moisture.

Other objects of the invention will be apparent from the description and claims which follow.

In conventional practice, cleaning and scouring compounds arecommonly packed for household use in containers of the'type comprising a fibrous body Wallhaving metallic ends crimped or otherwise secured to the fibrous body. In use, these containers are constantly brought in contact with wetted and heated surfaces such as sinks, drain boards, floors, stoves, and the like. If the containers are rested upon such surfaces on `their ends, themetal becomes rusty, with the result that the container becomes unsightly and leaves an unsightly mark upon all surfaces with which it is thereafter brought in contact.

If rested upon its sides, the brous body of the container, being of a highly absorbent nature, will absorb moisture from the contacted surface with the result that the body will very often collapse before the contents of the container can be used. Also, when rested on its sides, the fibrous body walls serve to transmit moisture to the contents of the container. In accordance with the present invention, an all-fibrous container is sealed at its ends in a manner to prevent contact of the container with damp surfaces, whether .the container berested on the ends or sides thereof.

Reference is had to the drawings in which like characters of reference are used to designate similar parts.

e Figure 1 is a perspective view, partly broken away, illustrating one type of fibrous containerl utilizing the sealing means of the present invention.

Figure 2 isa vertical sectional view of the container illustrated in Figure 1.

Figure 3 is an enlarged detail view of a section of the container shown in Figure 1 in which the (Cl. 22S-3.1)

container sealing means is more clearly exemsection, showing the improved end ledges of the container illustrated in Figure 4.

The container illustrated in Figures 1 to 3, comprises a tubular fibrous body wall I, closed at its ends by means of brous discs 2, annularly flanged at the peripheral edges as at 3. The discs 2 are invertedly inserted within the ends of body l in a manner to form peripheral marginal edges il at each of the container ends. Discs 2 may be suitably secured within body l, as at 5, by use of a suitable adhesive, between the surfaces of flanges?. and the inner Wall of body I. n

In accordance with the present invention a continuous bead 6 ,of congealable plastic Waterres'istant material, such for example, Celluloid, gutta-percha. synthetic resins, or the like is ap plied to the ends of the container, preferably in a manner to extend a suitable distance against the inner and outer side walls of the 'flanged which is supported against inward pressure by a somewhat thinner disc I0. Fibrous disc Il) is cupped, as at ll. TheY cupped edge Il is de-y signed to be inter-rolled, as at I2, with the rolled edge I3 of body I. I f

As shown in Figure 5 the rolled over portion I3A of body l is reinforced with a continuous bead 6 of congealable plastic water-resistant material.

Bead 6 comprises a continuous protecting ring and may be applied to the ends of the container in the form of a plastic through the medium of 'a suitable solvent. When applied in this manner, the solvent will readily evaporate from the mass leaving a'tough layer rigidly bonded to the marginal end flange 4 or roll I3, providing effective protection to the ends of the container.

The bead 5 also may be applied to the container ends by dipping or through the agency of suitable mechanical means. One means for applying a bead of this character is described in my copending application, Serial No. 54,181, led December 13, 1935, entitled Applicator.

It will be seen that containers treated in f tainers.

vaccordance with the present invention may be rested upon wetted or heated surfaces on their ends or on their sides without harm either to the containeror to the contents thereof.

The plastic compound forming bead 6 may be suitably tinted such that the bead 6, when applied to the container ends, will most attractively add to the appearance of the container. j

'I'he plastic bead 6 may be made of such thermo-plastic materials as natural or synthetic resins. In such instances, the bead may be ap-` plied through the agency of heat only, eliminating the necessity of a solvent.

An example of a material which may be employed in this manner is a mixture of natural resin with some suitable plasticizer, such as parain wax. If a glossy jet black surface is desired, a quantity of pitch may be included in the mixture. A mixture of such materials will melt to a liquid state at about the boiling point of water and may be applied to the container ends by simply dipping the edges of the container into the liquid material which cools and hardens upon contact with air.

A bead prepared from celluloid or a similar material may be preformed as a ring or ferrule of U shape and applied after the container has been assembled by'attaching the ring tothe edges by means of heat and mechanical pressure, no solvent or adhesive being necessary. As is well known, celluloid and materials of this character tion, a cupped'flbrous disc. and a iiat fiber disc,

are water-resistant and are relatively hard andelastic at temperatures approximately 185 F. and below.

The term brous, as used in the claims, will be understood to include ilber board, straw board, paperboard, pulp board, and other similar materials adapted for the manufacture of con- I claim: 1. In a container including a flbrous body and ',end closures, a bead of congealable plastic material relatively hard and elastic at temperaturesJ v'approximately 185 F. and below bonded to the Y having an end closure forming a peripheral marginal ange at the'container end,.a bead of congealable plastic material relatively hard and elastic at temperatures approximately 185 F. and below bonded to the flanged endof the container.
